Skan

In Lakota tradition, Škáŋ is the Motion of the universe. The Great Spirit, Wakȟáŋ Tȟáŋka, reflected upon himself and created the four Superior Spirits, Wi (the first to be created, bringing light to the world), Skan, Maka (Mother Earth) and Íŋyaŋ (the solid support of the Earth or the rock associated with the natural forces of the Earth).
